Do the hoses at the firewall both feel hot when the heater valve is open (heater controls set to maximum heat position ? Try disconnection the hoses at that go to the heater core put water from a garden hose into the hose going to the heater core as you get some one to move the heater controls from full hot to full cold, does the flow change, if not the heater controls may not be adjusted or functioning correctly allowing enough coolant to flow through the heater core. I have seen heater cores "plug up" when people use excessive amounts of stop leak to "cure " coolant loss.
